Abstract

Minyak nilam merupakan salah satu komoditas ekspor paling besar di Indonesia, akan tetapi saat ini kualitias dari minyak nilam masih sangat rendah hal ini ditandai dengan rendahnya kandungan patchouli alkohol sebagai kompenen utama. Tujuan dari penelitian ini yaitu untuk menganalisis komponen  utama minyak nilam (patchoulialkohol) secara cepat tanpa merusak sampel. Rancangan penelitian ini menggunakan model kalibrasi dan validasi pada patchouli alkohol dengan menggunakan Partial Least Square (PLS) sebagai bagian dari analisis Chemometrics. Hasil penelitian menunjukkan bahwa peningkatan performa kinerja PLS pada pretreatment multiplicative scatter correction dengan nilai RPD yang paling besar yaitu 302,5. Sehingga dapat tergolong ke dalam good model performance dengan nilai koefisien korelasi (r) yang tinggi 0,99, nilai koefisien determinasi (R2) yang bagus 83%, dan nilai error (RMSECV) yang paling kecil yaitu 0,02.

Abstract

Madrasah Ibtidaiyah Negeri 2 Banda Aceh is located under the Ministry of Religion of the Republic of Indonesia through the Aceh provincial regional office. Technology originating from smartphones and laptops has become something that is commonly used to facilitate the process of carrying out semester exams at these schools. The continuity of semester exams is an evaluation implemented by the school in assessing each student's ability to absorb subjects for 6 months. In 2022, students from grades 4 to 6 are expected to use smartphones or laptops to take semester exams complete with their respective internet quota data packages if using smartphones. This was approved by the school in its implementation after issuing several policies that had been agreed upon by the student's parents. The smartphone data package quota for each student is different, so the throughput produced on each smartphone has a different speed too. The method used in this research is an explanation by the presenter where the explanation is more about training to answer semester exam questions using a computer network system connected to the school's hotspot. The results of this community service activity are a solution to overcome problems with the internet network during semester exams. So that all students can answer the questions given by their respective class teachers.
